Abstract:
Various embodiments are disclosed relating to a memory circuit architecture. In an example embodiment, which may accommodate a change to a new memory size or cell aspect ratio, while migrating between different process nodes or the same process generation, while retaining at least a portion of the periphery circuitry, a memory circuit architecture may be employed in which the memory array is divided into an upper half and a lower half, thereby splitting the cache Ways among the two halves. The wordline may be split among the two array halves, with each half driven by a half wordline driver. Also, in another embodiment, two sets of bitlines may be provided for each column, including a contacted set of bitlines and a feed-through set of bitlines.
